Convert to improper fractions: Convert mixed numbers to improper fractions for easier calculation. Deion sprinted 16 3/10 laps, which is (16*10 + 3)/10 = 163/10 laps. He jogged 9 9/10 laps, which is (9*10 + 9)/10 = 99/10 laps. Subtract to find difference: Subtract the number of laps jogged from the number of laps sprinted to find the difference. 163/10 - 99/10 = (163 - 99)/10 = 64/10 = 6.4 laps.

Convert to improper fractions: Convert mixed numbers to improper fractions for easier calculation. Deion sprinted $16 \frac{3}{10}$ laps, which is $(16\times10 + 3)/10 = \frac{163}{10}$ laps. He jogged $9 \frac{9}{10}$ laps, which is $(9\times10 + 9)/10 = \frac{99}{10}$ laps.
Subtract to find difference: Subtract the number of laps jogged from the number of laps sprinted to find the difference. $\frac{163}{10} - \frac{99}{10} = \frac{(163 - 99)}{10} = \frac{64}{10} = 6.4$ laps.
